‘Ganghan’ is a high-yielding soybean (Glycine max L. Merrill) cultivar developedfor improved shattering resistance and suitability for mechanized harvesting. It was bredthrough pedigree selection after an artificial cross between ‘Taeseon’ (female parent) and‘Cheonga’ (male parent) in 2015. ‘Ganghan’ is a determinate type with an average mainstem length of 65 cm and first pod height of 19.6 cm, which is favorable for mechanicalharvesting. Compared to the control cultivar ‘Daewonkong,’ it showed stronger lodging toleranceand carried a genetic allele associated with pod shattering resistance. In diseaseresistance evaluations, it exhibited higher resistance than ‘Daewonkong’ to soybeanmosaic virus (G6H), bacterial pustule, and black root rot. Regarding seed quality, it contained38.8% protein, 17.6% oil, 86.1% unsaturated fatty acids, and 3,124 μg/g total isoflavones. The tofu yield was 232%, with mechanical properties and color comparable to ‘Daewonkong.’In fermentation processing tests, ‘Ganghan’ recorded a γ-PGA content of 11.4 mg/g andamino nitrogen content of 390 mg%, indicating potential use in traditional fermented soyfoods. In regional yield trials (RYT) conducted across 10 locations from 2020 to 2022,‘Ganghan’ had an average yield of 3.58 tons/ha, 14% higher than that of ‘Daewonkong’. Theadoption and expansion of ‘Ganghan’ is expected to contribute to increased domesticsoybean productivity, harvest efficiency, and cultivation stability under changing climateconditions, thereby improving the domestic soybean self-sufficiency rate (RegistrationNo. 10459).
